Answer: 0.95 kg/l
Density of Trex, [tex]d=60.0 lb/ft^3[/tex] (Given)
We need to find the density of Trex in kg/l.
We need to convert lb into kg and cubic ft to l.
we know that:
[tex]1 lb=0.45 kg[/tex]
[tex]1ft^3=28.32l[/tex]
Then, [tex]60lb/ft^3=\frac{60lb\times 0.45kg/lb}{1ft^3\times 28.32 l/ft^3}=0.95kg/l[/tex]
Therefore, the density of Trex is [tex]60lb/ft^3 or 0.95 kg/l[/tex]
